Formula

The Email List Growth Rate Calculator uses the formula:

List growth rate = (New subscribers - Unsubscribes) ÷ Total subscribers × 100

Worked example

For example, with new subscribers of 500, unsubscribes of 100 and total subscribers of 10,000, the list growth rate is 4.00%.

Inputs used
New subscribers 500
Unsubscribes 100
Total subscribers 10,000
Results
List growth rate 4.00%

Results are estimates for educational use, not professional advice.

Frequently asked questions

Subtract unsubscribes from new subscribers, divide by total subscribers, and multiply by 100. 500 gained and 100 lost on 10,000 is 4%.

Net growth matters more than gross sign-ups, since churn offsets new subscribers.

Any steady positive rate is healthy; lists naturally decay, so consistent net growth is the goal.

Offer valuable content, use signup incentives, and keep emails engaging to reduce unsubscribes.
